Brightness adjusting method, brightness adjusting device and terminal

Abstract

An embodiment of the invention discloses a brightness adjusting method which is applied on a terminal that is equipped with a display screen. The display screen is divided into a plurality of unit display areas. Each unit display area is provided with a corresponding temperature sensor. The brightness adjusting method comprises the steps of correspondingly detecting the temperature value of each unit display area through each temperature sensor; determining a target unit display area of which the temperature value is higher than a preset temperature threshold; determining whether the current brightness level of the display screen is lower than a preset brightness level; and if yes, reducing the brightness of the target unit display area. Correspondingly, the embodiment of the invention further discloses a brightness adjusting device and the terminal. The brightness adjusting method, the brightness adjusting device and the terminal have advantages of reducing consumption of light emitting material in the display screen and reducing display color difference.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method for adjusting brightness, an adjusting device and a terminal. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screen is a display screen made of organic light-emitting materials, wherein the organic light-emitting materials can emit colored light when electrified. In view of the advantages of thinness, lightness, large viewing angle and low power consumption, the OLED display screen is widely used in terminals such as smart phones. [0003] It should be pointed out that since the organic light-emitting material in the OLED display is self-illuminating, the light-emitting process will be accompanied by the consumption of the organic light-emitting material, and the consumption cannot be recovered. For example, in the process of displaying pictures on the display screen of terminals such as smart phones, ...

[0003] It should be pointed out that since the organic light-emitting materials in the OLED display are self-illuminating, the light-emitting process will be accompanied by the consumption of organic light-emitting materials, and this consumption cannot be recovered

For example, in the process of displaying pictures on the display screen of terminals such as smart phones, due to the complexity of the picture composition, it is inevitable that some areas will display dark brightness, some areas will display light brightness, or some areas will display for a long time, and some areas will display for a short time. , leading to different consumption of organic light-emitting materials in each area, and eventually resulting in display color difference of the display screen as time goes by, that is, it is impossible to display a picture with the same brightness
